Describe the bug

While playing music with spotify or apple music starting PorcupineManager making dramatic effect on music quality. I don't really know if I can call it a bug but testing wake word with for example with Alexa it works fine, music stays on a same level without additional noises. It sounds like you not only listening but also transmitting audio from microphone.

Steps To Reproduce

1. Play music on your iPhone with Airpods
2. In a app start initPorcupineManager and call start
3. Word detection works as expected
4. Verify small pause and then decreasing audio quality

Expected Behavior

Audio quality stays the same

Thanks for reporting I will let the team know but not really have an estimate for a fix. For now, you can use the low-level API Porcupine instead of PorcupineManager and handle audio management yourself.

@PaulLafytskyi - this was an issue with our ios-voice-processor package not supporting the latest Bluetooth profiles. We've patched the package and updated Porcupine-iOS with the fix. Grab the latest version (3.0.2) to try out the fix and let us know if it works for you.
